Life, Love, and Muscled Limph nodes?!?

So life, I't pretty good in all, I went on my second official date, and had a blast! Love, I LOVE my boyfriend to pieces! he is SO adorably cute! Muscled limph nodes?!? well here's the lowdown, Sunday (the day after my date) I was sitting in church, and I rest my chin on my hand while I'm listening, and there is a very sore lump under the right side of my chin! I was confused, but my limph nodes swelling isn't earth shatering. So I go to my parents house and have my mom look at it, she says it's fine, so I go to school the next day like normal. The lump gets a little bigger, but not much. That night it's hurting, so I have my mom look at it again, again she says it's fine and I probably have a toothache or a sorethroat that brought it on. The problem with that theory is that I haven't had a sore throat, and my teeth don't ache, or even tickle. The next morning my parents are at the hospital all day with a sibling sporting a high fever and random pains. The lump get substantially bigger, and is now a hard lump somewhere inbetween the size of a very large cherry, or a smallish golf ball. when I get home from school my dear mother, who had been up for over 48 hours, was sleeping and I was rather uninclined to wake her, so my older sister wrote a note telling my mom how worried she was about my lump. Before heading back to the hospital thismorning, she came into my room to check on me. she turned on my lamp, pointed it directly at my face and proceeded to poke my neck to find the darn thing. It had decreesed in size to about the size of a Costco cherry (the biggish kind) so she had me check and make sure my back teeth aren't infected, then she looks down my throat for inflemation, there was nothing abnormal with either, so I go to school with the lump still a mystery. It's almost smaller than a normal cherry now, and I'm hoping this means I won't have to have it checked by anyone besides my mom.
